Sorry to dispute but the current 15 year old I-20's I am replacing (currently in ground) due in fact have a 1" inlet. heads read I-20 ADV
Ok I am replacing I20's in my front yard due to cracking of cases. I ordered pgp to replace them. I thought they both have 3/4" inlets. But after the pgps showed up and I started to remove them low and behold I20s have a 1" inlet. Should I send back pgp and move to I25s or reduce down to 3/4"
